4 Reasons Why The Rotary Engine Is Dead
4 Reasons Why The Rotary Engine Is Dead. The Wankel engine was last seen in
a production car in the Mazda RX-8, and currently there are no rotary
engines in production. Mazda may bring it back in the RX Vision, however
there are many disadvantages to the rotary engine which has kept it from
being successful. Rotary engines have a low thermal efficiency as a result
of a long combustion chamber and unburnt fuel making it to the Exhaust. They also have problems with rotor
sealing as a result of uneven temperatures in the combustion chamber since
combustion only occurs in one portion of the engine. Oil consumption is
also a problem, as oil is injected to add lubrication and help keep the
rotor sealed. Finally, emissions are poor and fuel economy is terrible, and
ultimately this is the cause of it’s death.
